My princess pooch (or so she thinks) will park her rear on ANYTHING soft, so we are careful about what we leave laying around because she is so smelly. I used a thrifted flannel sheet and some old curtains from the Dude's room to make these. They are stretched over some 1 inch batting I had laying around and "quilted" with a few knots. Easy peasy, fully washable, and then I saw on Pinterest that Martha Stewart made the same thing. Mine are cuter though.
